WebApr 11, 2024 · This study showed that hepatic IDH2-deficiency had a highly significant effect on glucose metabolism. Hepatic IDH2-loss led to increased forward TCA cycle flux in fasting and refeeding states, as demonstrated by increased intermediates and enzymes in TCA cycle and ATP production. Glycolysis is coupled to the TCA cycle [9]. WebGlycolysis is the first pathway used in the breakdown of glucose to extract energy. It was probably one of the earliest metabolic pathways to evolve and is used by nearly all of the organisms on earth.
